LFO contour
By LFO Contour you can now bend
or ”morph” (almost) all the LFO
waveforms. A brief survey of the
LFO Contour options for the differ-
ent LFO modes follows:

Sine Contour morphs from sine to
a triangle wave (Contour to the

Square Contour modulates the
pulse width of the square wave.

Waves Contour ”zooms” into the
wave, thereby shortening the
wave’s loop length (Contour to the
right).

Clock
When you set it to OFF, the LFO
oscillates in the normal manner,
independently of the global Mas-
ter Clock (CLOCK TEMPO). When
you enter a note value here, the
LFO rate is synced up to the global
master clock. The length of the
waveshape’s cycle will then corre-
spond to the note value that you
have entered. You can also set the
rate via CLOCK TEMPO (refer to the
appropriate section) or synchro-
nize it to external MIDI clock.
